• openAccess   Adaptive precision solvers for sparse linear systems 

      Anzt, Hartwig; Dongarra, Jack; Quintana-Orti, Enrique S. ACM (2015)
      We formulate an implementation of a Jacobi iterative solver for sparse linear systems that iterates the distinct components of the solution with different precision in terms of mantissa length. Starting with very low ...
    • closedAccess   Tuning stationary iterative solvers for fault resilience 

      Anzt, Hartwig; Dongarra, Jack; Quintana-Orti, Enrique S. ACM. Association for Computing Machinery (2015)
      As the transistor’s feature size decreases following Moore’s Law, hardware will become more prone to permanent, intermittent, and transient errors, increasing the number of failures experienced by applications, and ...
